#=color(blue)(120#

Explanation:

#sqrt14400#

We prime factorise the number first (express the number as a product of primes):

#sqrt14400=sqrt(2*2*2*2*2*2*3*3*5*5)#

#=sqrt(2^6 * 3^2 * 5^2)#

#=(2^6 * 3^2 * 5^2)^(color(blue)(1/2#

#=(2^(6*1/2)) * (3^(2*1/2)) * (5^(2*1/2))#

#=color(blue)(2^3*3*5#

#=color(blue)(120#
